Biocidal sulfur-containing bis-imino carbamate compounds

Abstract

Sulfur-containing bis-amino carbamate compounds exhibit outstanding acaricidal, nematocidal and insecticidal activity.

What is claimed is: 
     
       1. A compound of the formula: ##STR24## wherein: n=1 or 2; R, R', R 1 , R 2 , and R 3  are individually alkyl groups of one to four carbon atoms;   R 4  is a group of the formula: ##STR25##  wherein: R 5  is dihydrobenzofuranyl, benzodioxolanyl, or benzothienyl group all of which may be unsubstituted or substituted with one or more alkyl groups.   
     
     
       2. A compound according to claim 1 wherein R 5  is a dihydrobenzofuranyl group. 
     
     
       3. A compound according to claim 1 wherein R 5  is a benzodioxolanyl group. 
     
     
       4. A compound according to claim 1 wherein R 5  is a benzothienyl group. 
     
     
       5. 2-[[N'-Methyl-N'-[N"-(2,3-dihydro-2,2-dimethyl-7-benzofuranyloxycarbonyl)-N"-methylaminosulfenyl]-carbamoyloxy]]imino-3-methoxyimino-N,N-dimethylbutyramide. 
     
     
       6. A compound according to claim 1 wherein: R', R, R 1 , R 2  and R 3  are individually methyl groups.   
     
     
       7. A compound according to claim 1 wherein: n=1.   
     
     
       8. An acaricidal, nematocidal or insecticidal composition comprising an acceptable carrier and as the active toxicant, an acaricidally, nematocidally or insecticidally effect amount of a compound of claim 5. 
     
     
       9. An acaricidal, nematocidal or insecticidal composition comprising an acceptable carrier and as the active toxicant, an acaricidally, nematocidally or insecticidally effect amount of a compound of claim 6. 
     
     
       10. An acaricidal, nematocidal or insecticidal composition comprising an acceptable carrier and as the active toxicant, an acaricidally, nematocidally or insecticidally effect amount of a compound of claim 7. 
     
     
       11. A method of controlling at least one member of insects, acarids and nematodes which comprises subjecting the insects, acarids or nematodes to an insecticidally, acaricidally or nematocidally effective amount of a compound of the claim 5. 
     
     
       12. A method of controlling at least one member of insects, acarids and nematodes which comprises subjecting the insects, acarids or nematodes to an insecticidally, acaricidally or nematocidally effective amount of a compound of the claim 6. 
     
     
       13. A method of controlling at least one member of insects, acarids and nematodes which comprises subjecting the insects, acarids or mematodes to an insecticidally, acaricidally or nematocidally effective amount of a compound of the claim 7. 
     
     
       14. An acaricidal, nematocidal or insecticidal composition comprising an acceptable carrier and as the active toxicant, an acaricidally, nematocidally or insecticidally effect amount of a compound of claim 11. 
     
     
       15. A method of controlling at least one member of insects, acarids and nematodes which comprises subjecting the insects, acarids, and nematodes to an insecticidally, acaricidally or nematocidally effective amount of a compound of claim 1.
